my fuel gauge is playing up, the reading keeps going up and down and generally settles on near full, as the wolf is 24 volt is it a standard defender sender unit to replace.
Thanks
Chris

I wouldn't have thought so, Chris. Pretty sure the sender is rheostat based, so putting 24 volts through a 12v sender would give incorrect resistance readings to the gauge. Resistance being equal to volts divided by current.

Thanks, I need to track down a new sender, may be I will find one at Newbury landrover day tomorrow.

I'm no electrical expert mind, Chris.

I went to Newbury Land Rover show to day and I asked several military people there, some said 12v and some said 24v, one guy told me to see if I could get a number of the fuel sender unit and he would tell me what it was. One man there who had military vehicles said you will be told you need 24v but a 12v will be fine, all confusing really. I did buy a very nice military tool kit though.

I think rheostats are designed to try and keep the current constant. So, I would have thought if the voltage was different it would create values the gauge wasn't calibrated for. @Kwakerman might be able to shed some light on it.
Sounds like you've had a good day though

Mine was doing the same (12v but they may work the same way). I fixed it by getting behind the dash and cleaning up the earth connection to the gauge and it now works reliably.

I cleaned up the connecters on the tank but I have not done the ones on the back of the gauge so I will try that.
Thanks
